In thermal energy, we saw that whenever there is a temperature gradient, a heat engine can be designed that converts thermal energy to work. According to the second law of thermodynamics, the efficiency of any heat engine can be improved by increasing the temperature differences between the two heat reservoirs. In the case of fossil or nuclear power plants, the chemical energy in the fossil fuel or the nuclear energy in the uranium is used as a heat source to boil water into steam. Solar power plants work in a similar fashion except that the heat energy comes from the sun.
